TruXedo TruXport Roll-Up Tonneau Cover Reviews


Best value cover

Reviewed By Curtis B (BEDFORD, TX) Reviewed for a 2015 GMC Sierra —5/23/2015 6:24 AM

This is my second Truxedo cover and it is a great cover. Holds down well and looks good. Easy to roll up and have full access to bed. Gas mileage went up about 1.5 mpg.

K&N 57 Series FIPK Air Intake (50-State Legal) Reviews


Well Worth It!

Reviewed By Kevin B (Casper, WY) Reviewed for a 2002 GMC Sierra —5/17/2015 6:47 PM

Easy to install. Getting 4 mpg better fuel mileage. Noticeably runs better. Will be switching back and forth to original when the winter weather returns. At a certain rpm the exhaust notice gets a little annoying, only down side. I just step on the gas a little more when that occurs.

It does what I expect and more

Reviewed By Erik R (Anza, CA) Reviewed for a 2009 GMC Sierra —5/16/2015 1:43 PM

Dang. I didn't realize there was a 500 character limit. So I will keep this short and sweet. Power 5 Ease of use 5 Tuneability 4 Instructions on what does what 3 If you don't care about your 0-60 times and yada yada buy this tuner. Oh! Do NOT adjust your tune if you have smog/state inspection coming up. They don't tell you that if you adjust parameters you will fail. It took about a week for my truck to go through the "GM cycle". Great buy, autoanything rocks
